Cuffs can also be sealed to protect the inner carcass. Trailing braided anti-static wires are also available. JF Hose & s Limited, Leyland Business Park, Centurion Way, Leyland, Preston,

2 SAND & GRAVEL MINING HOSE Consult JH Hose for the correct lining to suit your application pressure Nominal physical data A02, A12 Hand-built abrasion resistant suction and discharge hose. Sand and gravel pits, mining, coal, grain handling, mineral processing. 51mm to 406mm 12 metres. Smooth bore mandrel built. Two types of lining are available in thicknesses from 3mm to 12mm depending on the nature and severity of A tan coloured gumstock 40 hard natural rubber for fine air-bourne abrasives (A02) and a black reinforced 60 hard natural rubber for slurries and heavy abrasives such as gravel and rock (A12). Multiple layers of synthetic cord plus a single steel wire helix, giving a minimum 3.5:1 safety factor and a minimum 6 x bore size bend radius. Corrugated for greater flexibility. Tough weather and abrasion resistant. Two types are available, black natural rubber for normal use of black chloroprene (Neoprene) for more extreme external conditions. 10 bar working pressure Inch mm bar vacuum Higher working pressures are available upon request. Bore Nominal od Nom Min bend mm mm Kg/mtr radius mm Integral fixed rubber and fabric flanges with steel backing plates or beaded swivel ends are usually supplied where abrasive materials would excessively wear a steel hose tail.

3 DREDGER SEPARATE RING HOSE A20 Hand-built separate embedded ring suction hose. Designed for use on outboard of suction hopper and trailing suction dredgers where gimbal supports are used. These dredge hoses are capable of high angular deflection over short lengths. 300mm 1000mm 6 metres. A A mm thick lining 25mm thick lining A substantial carcass of high strength synthetic textile cords and extremely robust separate embedded rings embedded in solid rubber giving maximum resistance to crushing and vacuum collapse. pressure 10 bar Vacuum Full vacuum Inside diameter mm Weight Kg/mtr Ring spacing / / / / JF Hose & s Limited, Leyland Business Park, Centurion Way, Leyland, Preston,

4 DREDGER DISCHARGE HOSE A22, A23, A24 Hand-built dredger discharge hose. Designed for use as flexible connections in floating pipeline discharge. A range of pressure ratings and lining thicknesses are available depending on the duty required. 250mm to 400mm 12 metres. 500mm to 1000mm 6 metres. A substantial carcass of high strength synthetic textile cord plies embedded in highly resilient rubber, giving maximum resistance to pressure and flexing. This special reinforcement gives stability under pressure increasing the wear resistance of the lining. pressure A22 A23 A24 7 bar 10 bar 15 bar Inside diameter mm Approx od mm Weight Kg/mtr / / / / JF Hose & s Limited, Leyland Business Park, Centurion Way, Leyland, Preston,

5 DREDGER SUCTION AND DISCHARGE HOSE pressure/ vacuum A27, A28, A29 Hand-built dredger suction and discharge hose. Designed for use on dredger in many positions both onboard dredgers and for pontoon lines where a non-collapsible hose is required. 250mm to 400mm 12 metres. 500mm to 1000mm 6 metres. A substantial carcass of high strength synthetic textile cords and on an extra heavy duty tensile steel wire helix fully embedded in highly abrasion resistant rubber giving maximum resistance to crushing and vacuum collapse.
